I've always carried PT products with me. Great quality,performance, cheap, and reliability. I usually bring with me an Attitude, Blast, Rage, Eclipse, Pulsar and Impact II. When I can, I bring an headlight with me(Scout or Aurora). I know an headlight would seem strange but hey! We're flashaholics! With my EDC setup, I get over 250 hours of light since I also bring some spare batteries in a converted multitool knife belt pouch.
